STATIC DISCHARGE: Climates in some parts of the world are conducive to creating static electric build up (ESD). Your scale has been
designed to eliminate the damaging effects of ESD. In some extreme cases, ESD will be apparent on your scale by a lack of response or an
inability to turn off the unit. In the rare case that this occurs, simply disconnect the battery, wait 1 minute and reconnect the battery. The
scale will "reboot" itself and operate normally once the unit is turned on.
